We are staying at home alone on 25th, not even going to mass or visiting DAunt for a drink after (both set in stone when we stay at home rather than travel to DPs/DMIL). DH announced last night that teen DD can spend the day in PJs if she wants!! So that is a definite signal of intent.
I am meeting DSis next weekend for a walk and to exchange presents, she has offered to call to DMIL beforehand if there is anything to be collected, and to pass on what we have for them (I will also be getting the presents for DAunts and DUncles local to me to be passed on).
Passing on presents will be done at doorsteps before 25th.
And we might, if numbers are acceptably stable, go for a 1 day visit after Christmas itself - between 27th and 3rd Jan most likely,(although DSis has offered us the use of her house, and she will stay in DPs, if we want to stay overnight). But if we do go down, we have to visit both sides of the family, which means 3-4 households on each side (depending if DSIL and family are also visiting on 1 side, and if DB and family are still visiting on the other).
But numbers took a big jump yesterday, which hopefully was only a statistical jump and not the start of a trend, but it is exactly 2 weeks after our lockdown ended, so may well be the increases expected after that. In which case, I will meet DSis outdoors next weekend, as allowed, but we will probably not travel down to see everyone.
